Objectives : Yukmi-Jihwang-Tang(YJT) has been used in Oriental Medicine as a drug for tonifying and nourishing yin. So, the purpose of this Study was to investigate effects of Yukmi-Jihwang-Tang extract(YJTE) on the T-lymphocytes and peritoneal macrophages in mice. Methods : YJTE consists of the following components; Rehmaniae Radix Preparata(熟地黃), Dioscoreae Rhizoma(山藥), Corni-Fructus(山茱萸), Hoelen alba(白茯), Moutan Cortex Radicis(牧丹皮), Alismatis Rhizoma(澤瀉). Result : The results of this Study were obtained as follow; The administration of YJTE did not affect T-lymphocytes apoptosis. YJTE decreased sub-population of TH and TC cells, and proliferation of T-lymphocytes too. But YJTE accelerated phagocytic activity and Nitric Oxide(NO) production from peritoneal macrophages in mice. Conclusions : These results suggest that the administeration of YJTE suppresses T-cell mediated immunity, but activates peritoneal macrophages.

Staphylococcus aureus SA2, which was isolated from patient, is resistant to 10 usual antibiotics. The methanolic extracts of 21 well-known herb materials were combined with 10 antibiotics and applied to cheek inhibitory effects on the resistance of S. aureus SA2. The hexane fractions from methanolic extracts of Acori graminei Rhizoma and Anethi Fructus had most potent activity to inhibit the resistance of the bacteria when combined with ampicilin or chloramphenicol.

The study was performed to obtain the optimum extraction conditions for crocin from gardenia fructus. Generally crocin is unstable on heat, light, acid and base solution. The extraction efficiency of crocin from gardenia depended upon the extraction time, extraction temperature, pH in the extraction bath and the optimum conditions of crocin extraction were determined as 60 minutes of extraction time, 4$0^{\circ}C$ of extraction temperature, pH 7 of extraction bath. The molar extinction coefficient of crocin was 12,515 and the color yield of purified crocin was about six times higher than that of non-purified crocin. The heat-stability at extraction temperature and lightstability in irradiation with xenon lamp for one hour of the purified crocin were higher than those of non-purified crocin. Intensity of &{\lambda}_{max}&of crocin was decreased by irradiation for one hour but UV-Vis. spectra of crocin was not changed. The colors of purified and non-purified crocin dissolved wit methanol was evaluated by means of CIE L* a* b* system.

As a part of the quality control of herbal prescriptions which has been used for diabetes and related diseases, a reversed-phase liquid chromatographic method was developed for the simultaneous quantification of the three marker compounds, puerarin (Puerariae Radix), glycyrrhizin (Glycyrrhizae Radix), schizandrin (Schizandrae Fructus) in Oc Chun San. The HPLC analysis method was validated for parameters such as linearity, Limits of Detection(LOD), quantification(LOQ), repeatability, stability and recovery.

Atopic dermatitis is frequently encountered in the Dermatology clinic and the treatments are very various but the effects are not good enough. Especially in case of infants, taking herb med or acupuncture treatments are difficult so we would like to treat the atopic dermatitis using external therapy. We chose the oriental medicine textbooks and the oriental medicine journals that external therapy was used and divided into Yugobub(油膏法), Buchubbub(敷貼法), Sechukbub(洗滌法). The results were as follows: 1. In the frequency of medicine was Coptidis Rhizoma(黃連), Phellodendri Cortex(黃栢), Sophorae Radix(苦蔘), Cnidii Fructus(蛇床子), Allumen(枯礬) etc. 2. The effects of medicine were Chungyul(淸熱), Haedok(解毒), Zosub(燥濕), salchung(殺蟲), Gupung(祛風), Jiyang(止痒) etc.

In the course of screening for substances inhibiting apoptosis of U937 human leukemia cells induced by etoposide ($10\;{\mu}g/ml$), Forsythiae fructus, which showed a high level of inhibition, was selected. The regulating compounds were purified from the ethyl acetate extract by silica gel column chromatography and HPLC. The active substance was purified and identified as rengyolone by spectroscopic methods. This compound showed inhibitory activity on caspase-3 induction, a major protease of the apoptosis cascade, with an $IC_{50}$ value of $38.96\;{\mu}M$ after 8 h of etoposide treatment in U937 cells. The expression level of caspase-3 and poly(ADP-ribose) polymerase (PARP) were dose-dependently inhibited by the compound, suggesting that rengyolone inhibits etoposide-induced apoptosis via downregulation of caspases.

Folk Remedies symbolize the medical art of the common people, and contain their special emotion and colloquial expressions. They are medical treatments in which the medical history and the tradition and the soul of a people are incorporated. They are handed down in various ways. This study introduces some of folk remedies. For example, powder of tigers' bones heals neuralgia. Rice wine brewing up with ginger is effective in a cold. Water boiling with safflower does good in neuralgia. Pasting herba houttuyniae takes effect in skin disease. To Decoct and drink old hardy orange is effective in urticaria. Water boiling with fructus corni alleviates a fever. Camellia oil or rhizoma cnidii or iris is used for the extermination of vermin and the antiseptic. In the end, the practical application of these remedies to the resources of industry and education will be discussed.

Six heavy metals (lead, copper, cadmium, chromium, mercury and arsenic) were analyzed in 9 oriental medical materials(Paeoniae Radix Alba, Zizyphi Fructus, Cnidii Rhizoma, Rehmanniae Radix Preparata, Angelicae Gigantis Radix, Astragali Radix, Glycyrrhizae Radix, Cinnamomi Cortex Spissus, and Zingiberis Rhizoma Crudus) by inductively coupled plasma atomic emission spectrometry (ICP-AES). The heavy metal contents of Zingberis Rhizoma Crudus and Angelicae Gigantis Radix were 44.0 and 37.3 mg/kg, respectively, which were 1.47 and 1.24 times higher than the guideline set by the Korean Food and Drug Administration (KFDA). Washing with deionized water lowered the heavy metal contents by 20-38%, and reduced levels to below the guidelines set by KFDA.

Maduryung Extract, one of herbal medicine was tested for inhibitory effect to alcohol, acetaminophen and d-galactosamine induced hepatitis in rats. The results were as follows. 1. Increaced serum GOT, GPT levels by alcohol were significantly decreased by Maduryung extract.(p<0.01) 2. Maduryung extract decreaced GOT value in acetaminophen induced hepatitis and this effect may be due to increace of GSH level in liver tissue.(p<0.05) 3. Repeat administration of Maduryung extract showed inhibitory effect on s-GOT, s-GPT levels in d-galactosamine induced hepatitis. (p<0.05) According to the above results, it seems that Maduryung could be use as drug for alcohol or drug induced hepatitis treatment.

Osteoblasts play an important role in bone metabolism by bone formation. Natural medicines having a stimulatory activity on osteoblast proliferation and differentiation can improve bone diseases such as osteoporosis. The methanol extracts of 159 herbal medicines were screened for the stimulatory activity on osteoblast proliferation by MTT assay and differentiation in the presence of ascorbic acid and $\beta$-glycerophosphate. Among the tested extracts, Alpiniae Semen, Amomi Semen, Anemarrhenae Rhizoma, Bambusae Folium, Cannabis Semen, Dalbergiae odoriferae Lignum, and Luffae Fructus Retinervus showed relatively strong stimulatory activity on osteoblast proliferation, whereas Amomi Semen showed strong stimulatory activity on osteoblast differentiation.
